Groundwater Management Associates, Inc. (GMA) is working with the County to provide professional consulting services associated with the drilling, construction, and testing of one water supply well adjacent to the Mainland Water Treatment Plant, Maple Road, Maple, Currituck County, NC. If successful, the new water -supply well will become a new source of raw water for the reverse osmosis WTP. New water supply well RO4 will be constructed in the Yorktown Aquifer. The enclosed permit application includes the GW-22W form, 2021 Currituck County - Mainland Water Department Local Water Supply Plan, a diagram of the proposed well construction, maps detailing location, site features, and parcel information, and a copy of the January 25, 2022, Well Site Approval letter issued by the NCDEQ Public Water Supply Section. The water supply well will be constructed of SDR17 PVC casing, and stainless -steel screens, and built according to the North Carolina Well Construction Standards (NCAC 02C). Casings will be properly grouted to prevent interconnection of the aquifers. A Certified Well Contractor will be contracted to perform the drilling operations. Our plan is to have the drilling contractor begin Mr. White Page 2 drilling operations by June 15t, 2022, pending receipt of the well construction permit. Your help with meeting our proposed timetable would be appreciated.

(GMA) has been contracted by Currituck County (the County) to assist in their efforts to construct one additional public water -supply well (Mainland Well #4). GMA will oversee the design, construction, and testing of one Yorktown Aquifer water -supply well located adjacent to the Mainland Water Treatment Plant, Maple Road, Maple, Currituck County, NC. If successful, the new water -supply well will become a new source of raw water for the WTP. The proposed Currituck County water -supply well, currently identified as "WELL #4", can be found in the attached figures. We request well site approval of the well location. Introduction The proposed water -supply well (WELL #4) will be located south of the WTP on the adjacent property (see attached map). The property is owned by Currituck County. The proposed well will be located in the northern portion of the property with wooded, vacant land located to the west and south, the WTP to the north, and Maple Road and the Currituck County Regional Airport to the east. The proposed water -supply well location is as follows: "WELL #4": 36.395228°,-76.021892° A FEMA National Flood Hazard map, a map depicting surveyed wetlands by Land Management Group, and site maps of the proposed well are attached. Mr. Joey White December 14, 2021 Page 2 Potential Sources of Pollution GMA met with the County representatives, performed a site reconnaissance visit on December 9, 2021, accessed available public records, and obtained an Environmental Data Records (EDR) search for the site to identify potential sources of contamination that could adversely impact the placement of a well. The environmental data records search was conducted by Environmental Data Research Inc. (EDR) and completed on November 30, 2021. No mapped sites of concern were found and the site was not listed in any of the databases searched by EDR. A copy of EDR report is attached. GMA has completed our due diligence and believe that the well site meets the setback and environmental compliance requirements as follows per the 15A NCAC 02C .0107 STANDARDS OF CONSTRUCTION: WATER SUPPLY WELLS: • The proposed water -supply well is not located in any area where surface water or runoff will accumulate around the well due to depressions, drainage ways, and other landscapes that will concentrate water around the well. See the attached figure from FEMA's Flood Hazard Viewer. • No single-family dwelling with septic tank and drainfield, including the drainfield repair area is located within 50 feet • No single-family dwelling with septic tank and drainfield, including the drainfield repair area in saprolite system as described in 15A NCAC 18A .1956 is located within 100 feet • No other subsurface ground absorption waste disposal systems are located within 100 feet. • No industrial or municipal residuals disposal or wastewater -irrigation sites are located within 100 feet. • No industrial or municipal sewage or liquid -waste collection or sewer main, constructed to water main standards in the American Water Works Association (AWWA) Standards C600 and/or C900, is located within 50 feet. • No water -tight sewer lateral line from a residence or other non-public system to a sewer • main or other wastewater disposal system is located within 25 feet • No other sewage and liquid -waste collection or transfer facility are located within 100 feet. • No cesspools and privies are located within 100 feet. • No animal feedlots, as defined by G.S. 143-215.106(5), or manure piles are located within 100 feet. • No fertilizer, pesticide, herbicide or other chemical storage areas are located within 100 feet. • No non -hazardous waste storage, treatment or disposal lagoons are located within 100 feet. • No sanitary landfills, municipal solid waste landfill facilities, incinerators, construction and demolition (C&D) landfills and other disposal sites except Land Clearing and Inert Debris landfills are located within 500 feet. • No Land Clearing and Inert Debris (LCID) landfills are located within 100 feet. • No animal barns are located within 100 feet. Kelley A.

The proposed well has been assigned a Water System Facility (WSF) Identification Number and Sampling Point Code as indicated below. WSF ID No. Sampling Point Code Description of Well Site Preliminary Latitude and Longitude RO4 R32 RO Well No. 4 36°23'42.933" /-76°O1'18.811" This letter is provided by Public Water Supply (PWS) Section, in accordance with rule .0305(b) of the Rules Governing Public Water Systems (15A NCAC 18 C), to provide permission to drill a well at the listed sites in order to establish water quality and quantity and suitability of the wells as a source for a public water system. In addition, this "preliminary well site approval" is to acknowledge that according to the information and documentation provided, we understand that the proposed wells are located on a lot so that the area within 100 feet of the well will be owned or controlled by the person supplying the water and that the supplier of water will protect the well lot from potential sources of pollution and construct landscape features for drainage and diversion of pollution as required in rule .0203(1). In addition, per the information provided by Mr. Kelley Smith, PG of Groundwater Management Associates dated December 14, 2021, it has been determined that the proposed well location satisfies the minimum horizontal separation distances specified in rule .0203 (2) and summarized in the following table: D_ECAROUNA °w.ma,i or Ernmrasl a.u� /`. North Carolina Department of Environmental Quality I Division of Water Resources Washington Regional Office 1943 Washington Square Mall I Washington, North Carolina 27889 252.946.6481 Distance (in feet) Potential Source of Pollution 100 • • • • • From any sanitary sewage disposal system, sewer, or sewer pipe (unless sewer is constructed of water main materials and joints, in which the sewer pipe shall be at least 50 feet from the well. From buildings, mobile homes, permanent structures, animal houses or lots, cultivated areas to which chemicals are applied. From surface water. From a chemical or petroleum fuel underground storage tank with secondary containment. From any other potential source of pollution not listed in this table. 200 • From a subsurface sanitary sewage treatment and disposal system designed for 3,000 or more gallons of wastewater a day, unless your well water source is a confined aquifer. 300 • From any cemetery or burial ground. 500 • • • • From a septage disposal site. From a chemical or petroleum fuel underground storage tank without secondary containment. From the boundary of a ground water contamination area. From a sanitary landfill or non -permitted non -hazardous solid waste disposal site. 1,000 • From a hazardous waste disposal site or in any location which conflicts with the North Carolina Hazardous Waste Management Rules cited in NCAC 13A. We also understand that the owner will ensure that the lot is graded or sloped so that surface water is diverted away from the wellhead and that the well shall not have greater than a 1 percent chance of flooding in accordance with 15A NCAC 18C .0203(a)(4). PWS Section "Authorization to Construct" and "Final Approval" Subsequent to well drilling and evaluating water quality and quantity (e.g., collecting and analyzing samples and performing a 24-hour well drawdown test) the owner must submit an "Application for Approval of Engineering Plans and Specifications For Water Supply Systems" to document proposed well completion (e.g., selected pump, wellhead and well house details) and associated transmission lines, treatment and/or storage facilities and other critical information about the public water system. In accordance with rule .0305(a) no construction shall be undertaken until the PWS Section issues an "Authorization to Construct" letter. In addition, in accordance with .0309(a) the new well and all associated treatment, storage or transmission/distributions lines shall not be placed into service until the PWS Section has issued a "Final Approval," These steps are described in the Engineering Planning and Development Guidance Document available at https://files.nc.gov/ncdeq/Water%20Resources/files/pws/planreview/EPD Guidance JuIy2019.pdf "� at o.eaCt011I or Enwoivne,maaHN/`d North Carolina Department of Environmental Quality 1 Division of Water Resources Washington Regional Office 1943 Washington Square Mall I Washington, North Carolina 27889 252,946.6481 Be aware that plans, specifications and reports for the new wells must be certified by a Professional Engineer. Therefore, it is recommended that a Professional Engineer or Licensed Geologist (or their designated representative) experienced in the construction of water supply wells, conduct on -site monitoring of well construction. At a minimum, certain critical phases of well construction such as installation and grouting of casing should be monitored. In many situations it may be necessary to go beyond the minimum requirements in order to protect the public health and ground water resources. Other Agency Approvals Required This PWS Section "preliminary well site approval" letter does not address other agency applicable rules and requirements pertaining to well construction and registration. Local county well construction rules and ordinances may include additional requirements. Well construction must meet the standards specified in the Well Construction Standards (15A NCAC 2C). Be aware that these rules require a permit to be obtained from the Water Quality Regional Operations Section of the Division of Water Resources before the well is constructed if it is anticipated that the new well will be part of a water system with a design capacity of 100,000 gallons per day or greater. In addition, these rules require that wells be constructed by a properly certified well driller.
